ethylene glycol (EG) is an important organic chemical raw material, which is widely used in the production of various chemicals and polymers. In the field of chemical production raw materials, ethylene glycol, as a driving material, is closely related to many upstream and downstream products. The following are some upstream and downstream related products related to ethylene glycol:

Upstream products:

1. Ethylene: Ethylene glycol is mainly produced by ethylene oxidation, so ethylene is one of the main raw materials of ethylene glycol.
2. Oxygen: Ethylene glycol production process requires the use of oxygen oxidation reaction.

downstream products:

1. Polyester (PET): The reaction of ethylene glycol and terephthalic acid (PTA) can produce polyester. Polyester is a polymer widely used in the production of materials such as fibers, films and containers.
2. Glyoxal: Ethylene glycol can be heated under acidic conditions to generate glyoxal, which is an important chemical raw material for the production of drugs, spices, etc.
3. Glycol Ethers: Glycol can react with alcohols to form glycol ethers, which are excellent solvents and chemical reaction intermediates.
4. Antifreeze: Ethylene glycol can be used as an antifreeze after mixing with water, which is used in the cooling system of automobiles and other mechanical equipment.

In short, ethylene glycol, as an important organic chemical raw material, is closely related to many upstream and downstream products, and plays an important role in the field of chemical production raw materials.
